In daily production control, the operator must understand the principle of the G7 process, master the meaning of the concept of neutral gray density, HR, HC, SC, etc., but also have their own experience of the G7 process, which often requires a certain amount of operation and accumulation. Can be reached. For example, when the CMYKRB six color chromaticity values ​​are up to standard and the G chromaticity values ​​are not up to standard, what should the operator do? At this time, experience has played a crucial role. First, G is a color mixture of Y and C, so the density of C and Y should be increased or decreased, and the increase or decrease of Y density has little effect on the L value and a value of Y, which mainly causes the increase and decrease of b value. At this time, if the b value of G has a large deviation from the standard value, the Y color density value should be mainly added and subtracted to control, while the C color density value is kept unchanged.
The operator only has a deep understanding of the G7 process principle, and after a certain period of training and exploration, and at the same time master the complex data change relationship of each control point, can better use the G7 process and make it the largest in production. effect. Of course, in actual production, the operator must also choose the data according to the actual situation. After all, the production is not the certification. The data at this time is only to help control.
Printing equipment, if necessary, experienced operators should also improve the standard according to product characteristics and personal understanding, such as increasing density, increasing the contrast of the original or increasing the saturation of the original, to bring some of the results beyond the standard.
